The resulting silk is soft, light and lustrous, and is twisted to produce the strands of silk yarn. Silk is a natural protein fiber, some forms of which can be woven into textiles.The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. Silk production is nothing but one out of the several stages through which the silkworm goes through during its life cycle, finally unraveling the most desired and loved silk thread out of a cocoon. The Process Of Making Silk - May 21, 2018 - First step: Silk Reeling The silk is extracted from the cocoon and becomes the raw material for the fabric. The protein fiber of silk is composed mainly of fibroin and is produced by silkworms larvae to form cocoons. In this way, Silk is prepared from Silkworm. The more number of weft yarn reeled together, the heavier the silk fabric becomes. Dye silk thread in a dye bath. It starts by raising silkworms and then processing the fibers they produce. This is where cocoons are turned into silk threads through a four-step process. Once the worms. Th… Step 2: Thread extraction. Post rearing of silk worm into cocoons by farmers the cocoons are bought to their near silk cocoon markets and auctioned.

The front of the fabric has shimmery satin weave while the back is flattened crepe, or simply wrinkled woven fabric. Then the sericin or silk gum holding the cocoon's filaments together is softened by alternating hot and cold immersions. The degumming process leaves silk lustrous and semitransparent, with a smooth surface that does not readily retain soil. Each Thai silk cocoon can give about 700 yards long of filament.

After this process, there is also a bleaching and drying process before the threads are good for hanging out to dry the beautiful color variations of the yarn, ready for spinning onto bobbins. shuttle alternately back and forth, sending the wooden shuttle flying from side to side by pulling on a cord while simoultanously beating up the weft yarn. 2-ply, 4-ply, 6-ply is often used to indicate the weight of Thai silk fabric.

The introduction of silk made a significant impact on these societies. The filament begins to unwind, forming an extraordinarily long thread of great strength yet as delicate as a spider’s web.

Silk is sometimes—in a process called weighting—treated with a finishing substance, such as metallic salts, to increase weight, add density, and improve draping quality. Silk yarns must be washed and degummed by immersing the skeins in large tubs of hot water. Young silkworms are fed fresh mulberry leaves several times a day. Scale (I have a scale for weighing fiber amounts and a more precise … Generally, weaving involves interlacing two sets of threads so that they lock around each other and create a strong, uniform piece of fabric.
